Q: Please let me know about my sister and her daughter if they have any jinn on them, because they always fall sick and get scary dreams. Please make istikhaara and let me know if they have any jadu or asraat.
A: Recite the four Quls and Aayatul Kursi after your five daily Salaah and before retiring to bed. Allah Ta’ala will protect you from all evils.
